ActivityUtil

ActivityUtil是一个封装Activity跳转的工具类

Gradle

android support

dependencies {
    implementation 'com.yuri.activity:activity_util:<latestVersion>'
    ...
}

如果你在使用AndroidX，你可以使用下面的这个

dependencies {
    implementation 'com.yuri.activity:activity_util_x:<latestVersion>'
    ...
}

功能

• 不再需要重写onActivityResult代码
• 链式代码结构，所见即所得

#使用说明 简单的startActivity跳转示例

ActivityUtil.with(MainActivity@this)
        .activity(TestActivity::class.java) //跳转目标
        .start()

带参数的startActivity跳转示例

 ActivityUtil.with(MainActivity@this)
        .activity(TestActivity::class.java) //跳转目标
        .withString("text", "startActivity")
        .start()

简单的startActivityForResult跳转示例

ActivityUtil.with(MainActivity@this)
        .activity(TestActivity::class.java)
        .withString("text", "startActivityForResult")
        .startResult()
        .filter(OnResultFilterFunc()) //过滤RESULT_CANCEL，只有RESULT_OK的才会回调
        .subscribe {
            val data = it.data
            val text = data?.getStringExtra("result")
            textViewResult.text = text
        }

更多startActivityForResult跳转示例

val list = arrayListOf<String>()
list.add("Test")
list.add("for")
list.add("activity")
val bundle = Bundle()
bundle.putStringArrayList("list", list)
ActivityUtil.with(MainActivity@this)
        .activity(TestActivity::class.java)
        .withString("text", "startActivityForResult bundle")
        .withBundle(bundle)
        .startResult()
        .filter(OnResultFilterFunc())
        .subscribe {
            val data = it.data
            val text = data?.getStringExtra("result")
            textViewResult.text = text
        }

默认startActivityForResult是可以不需要设置requestCode的、

如果需要可以这样做

ActivityUtil.with(MainActivity@this)
        .activity(TestActivity::class.java)
        .requestCode(123)
        .withString("text", "startActivityForResult")
        .startResult()
        .filter(OnResultFilterFunc())
        .subscribe {
            if (it.requestCode == 123) {
                val data = it.data
                val text = data?.getStringExtra("result")
                textViewResult.text = text
            }
        }
